Aspherical submersible 1.87 m in radius, armed with multiple cameras, descends under water in a region of the atlantic ocean known for shipwrecks and finds its first shipwreck at a depth of 1.84 ✕ 103 m. seawater has density 1.025 ✕ 103 kg/m3, and the air pressure at the ocean's surface is 1.013 ✕ 105 pa.
(a) what is the absolute pressure at the depth of the shipwreck?
pa

(b) what is the buoyant force on the submersible at the depth of the shipwreck? (give the magnitude.)

The concepts that we need to apply in this problem are the Pressure in a liquid at a given depth, that is hydrostatic pressure and the force in terms of density, volume and gravity.

The hydrostatic pressure is given by,

Where

is the pressure at the top

is the density

g = gravity force

D = The distance from the top.

Part A )

Part B) The force in terms of density, volume and gravity is

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
